Amulet of Raiden
Raiden's Amulet is a mystical tailsman belonged to the Earthrealm's thunder god Raiden. This golden, sapphire amulet was originally created by the Elder Gods and was given to Raiden as a gift. At the end of Mortal Kombat Armeggedon the amulet was destroyed by Shao Kahn. Raiden, using the last of his energy and the last of the amulet's magic sent a message back in time to his past self to prevent armegeddon from happening. The closer armegeddon came to happening, the more the amulet in the new timeline cracked, but ultimately Shao Kahn was destroyed once and for all and the cracks were repaired.
